I have had some eye issues as well. I have incredibly good eyesight. But I have floaters in my eyes sometimes.. Looks like tadpoles swimming in your eyes. I am allowed to train but several times a year I go to a retinal specialist and get a flourizine(check spelling) dye test. Basically, they shoot carrot dye in your arm and then take pics of your eye and look for scar tissue. If there is new scar tissue I take it easy for a while and if it is stable or decreasing then I go about training as normal. If you "google" macular degeneration you can get more info.

I'm near sighted and because of the tears and retinal problems, see a specialist regularly. Because I teach and students don't always have the greatest control (particularly when you're trying to make the training as realistic as possible), I end up doing what RangerG does, doing a lot of face blocks. Talked to my doc and she said pretty much that if there are any changes to let her know and she'll take a look but my condition isn't related to my training.
